Is sales tax calculated before or after the 50% discount?
Sales tax is always calculated after the discount is applied. For your $900 purchase with 50% off, you first calculate the discounted price ($450), then apply the sales tax to that amount.
For example, with an 8% sales tax: $450 × 1.08 = $486. This means you save on both the purchase price and the tax amount, since tax is calculated on the lower discounted price rather than the original $900.
Should I use a credit card rewards program for this $450 purchase?
Yes, combining your 50% discount with credit card rewards can maximize savings. If your card offers 2% cashback, you'll earn an additional $9 back on your $450 purchase. Combined with your $450 discount savings, your total savings would be $459.
Some cards offer higher rewards (3-5%) in specific categories. Shopping portals can add another 1-10% cashback. However, only use credit cards if you pay the balance in full - interest charges would negate any savings from the discount and rewards combined.
